In 7.4 they where indeed guidelines. In 8.x the semantics of the 
function attribute are meant to be enforced. I quote Tom from this 
thread: "You don't have a lot of room to complain because 8.0 started to 
enforce that.".

The "user" in this context, is the user of the function attribute, i.e. 
the function developer. Sorry if I was unclear.

Right, I also preferred 7.4 since I consider it less ambiguous then the 
current solution. But a much better solution is just around the corner 
and it would be unfortunate if some fairly rare scenarios are used as an 
argument to prevent it. Especially since those scenarios can be easily 
catered for by introducing a fourth type.
